The fast-growing 6G communication technology is enabling the transition from serving people and things to supporting the “Internet of Everything” [1]}, [2]}, [3]}. Specifically, 6G communication technology serves intelligent production and life through intelligent interconnection and collaborative symbiosis of human-machine-object, and actively promotes the construction of an inclusive and intelligent human society [4]}, [5]}, [6]}. In the 6G era, however, the traditional point-to-point information transmission communication system, that relies on the resource optimization of physical-layer dimension and the stable transmission protocol at the network layer, cannot meet the increasing requirements of complex, diverse, and intelligent information transmission needs, e.g., supporting virtual reality, holographic projection and Metaverse applications [7]}, [8]}. Therefore, it is essential to design a new communication paradigm for efficient information transmission thus meeting the demands of future communication.
